For roughly $3 each, I can enjoy any fragrance I want by dabbing a little onto my wrist. It lasts for hours. And I only need to use about .05ml each time. Nobody else can smell it but me obviously, but that's not an issue.
I use the 4 bottles for dates or social events where I want to smell good for other people.
The point of my story is, if you don't really care if others can smell a scent on you, you can get close to owning just about every fragrance out there, niche or designer.
